Abstract: A reward determination system determines distribution of a reward received from a data user to reward distribution targets in a platform for distribution and utilization of biological data provided by data providers. Each reward distribution target has: development task information obtained by quantifying a workload of a task required for developing the platform into numbers; data provision task information obtained by quantifying a workload of a task required for providing the biological data into numbers; and data processing task information obtained by quantifying a workload of a task required for processing the biological data into numbers. A reliability parameter and a contribution parameter of each task are calculated based on the development task information, the data provision task information, and the data processing task information on each task, and a reward to be allocated is determined for each reward distribution target based on the reliability parameter and the contribution parameter.

Abstract: Performance of an electronic apparatus is improved. A terminal of the electronic apparatus includes: a first metal layer made of aluminum; and a second metal layer which is arranged on the first metal layer, which is bonded to a cap film and which is made of titanium. The cap film includes a metal film which is made of titanium and is bonded to the second metal layer. The metal film includes: a contact portion which totally covers a portion of the metal layer ML3 of the terminal, the portion being exposed at an opening of an insulating layer from the insulating layer; and a peripheral portion which is arranged outside the opening and which continuously surrounds the contact portion in plan view. The insulating layer intervenes between the peripheral portion of the metal film and the terminal.
